MEANS FOR PREVENTING CLOGGING 0F CORN-BINDER PACKER-ARMS.

SPECIFICATION forming part of Letters Patent No. 696,203, dated March25, 1902.

Application filed Mayd, 1901. Serial No. 58,905. (No model.)

To all whom it may concern:

Beit known that I, JOHNB. SHAW, of Litchfield, Meeker county, Minnesota,have invented certain new and useful Improvements in Means forPreventing the Clogging ofCorn- Binder Packer-Arms, of which thefollowing is a specification.

The invention relates to attachments forcorn-harvesters, particularly ofthe vertical The object of the invention is to provide means forpreventing clogging of the packerarms and the consequent annoyance anddelay resulting therefrom.

The invention consists generally in various constructions andcombinations, all as hereinafter described, and particularly pointed outin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a detail of a portion of a corn-harvester with my in ventionapplied thereto. Fig. 2 isa horizontal section showing the lowerpacker-arm and the wing or shelf over which it operates.

In the drawings, 2 represents a portion of the floor on which the stalksmove in an upright position.

3 is an upright plate forming the wall on one side of the plate 2. Abovethis plate is a board 4, and between them thelower packerarm 5 operatesupon a packer crank-shaft 6. The packer-arm projects into the space overthe floor 2 between the plate 3 and the board 4 and pushes the stalksback over the floor to the point Where they are bound. This packer isprovided with an arm 7, that is pivotally connected with a standard 8bya link 9. The revolution of the crank-shaft 6 imparts a gyratingmotion to the packer-arm ,and causes it to be alternatelywithdrawn fromand projected into the space occupied by the moving stalks of corn. Asordinarily constructed the plate 3 will catch the pigeongrass brought inby the cornstalks, and the heads of the grasses I dropping over the edgeof the plate will be hung thereon until a sufficiently large bunch isformed to clog the packer-arm and prevent its operation. These bunchesof grass will collect quite frequently and stop the movement of thepackers and necessitate stopping the machine,'clearing it of the corn,and pulling or picking out the grass from the clogged parts. As more orless grass is mixed with the growing corn it will clog the packers in ashort time, and as it is almost. always necessary to clear away.

the obstruction by hand it follows thatagreat deal of time is lost inthe operation of the machine; All this difficulty and objection I haveobviated by providing a shelf or wing 10, arranged horizontally beneaththe packerarm 5 and preferably extending laterally from the top of theplate 3. The packer-arm operates over this wing, and as the grasses arebrought in by the cornstalks and are deposited on the top of the plate'Sthe heads will lie on the flat surface of the wing, and when the cornpasses back over the packerarm and out of the machine it will carry thegrass along with it, there being no edges or corners on the plate 10upon which the grass can lodge. I have demonstrated by actual tests thatthis wing will absolutely prevent any grass that may be brought into themachine from lodging beneath the packer-arm and clogging the same.

I do not confine myself to any particular width of wing; but it shouldbe sufficiently wide so that there will be no danger of the heads of thegrasses lodging on the outer edge of the wing.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a corn harvester and hinder, the combination,with an upright plate 3, of a board 4 above the same and spacedtherefrom, a crank-shaft, a packer-arm thereon operating through thespace between said plate and said board, and a horizontal wing providedon theupper edge of said plate between it and said shaft, for thepurpose specified.

2. In a corn harvester and binder, the combination, with a .floor 2whereon the cornstalks move in an upright position, of a plate corn fromlodging on the upper side thereof, whereby clogging of the packer-arm isprevented.

3. In a corn harvesterand hinder, the combination, with a vertical wallpast which the corn moves in an upright position, of a crankshaft, agyrating packer-arm mounted on said shaft, and adapted to overhang saidwall and engage the stalks of corn, and a horizontal wing provided atthe upper edge of said wall nearsaid arm and between said wall andshaft, said wing being of suflicient width to prevent the grass broughtin by the corn from lodging thereon and on the edge of said wall andclogging said packer-arm.

4. In a corn harvester and binder, the combination, with a floorprovided with an upright wall past which the cornstalks are moved, of acrank-shaft near said wall, apackerprovided on said shaft and having anarm 7, an upright standard 8 near said wall, alink connecting saidstandard and said arm, and a horizontal wing or plate provided on theupper edge of said wall near said packer and extending laterally beneaththe same to prevent the grasses brought in by the corn from lodging onsaid wall, substantially as described.

In witness whereof I have hereunto set my hand this 2d day of May, 1901.
